author
Known only by the pen name "Normanus," this elusive author is remembered for a richly illustrated guide to one of London's historic churches. Very little personal information survives, which gives the work an extra air of mystery.
Normanus is the credited author of An Illustrated Account of St. Bartholomew's Priory Church, Smithfield, a historical work that is available through Project Gutenberg. The book presents the story of St. Bartholomew's Priory Church in London and also includes material on Bartholomew Fair, St. Bartholomew's Hospital, and Canonbury Tower.
The available records found here identify "Normanus" as the author name, and list G. J. Evans as the illustrator. Beyond that, reliable biographical details are scarce, so it is safest to treat "Normanus" as a pen name or authorial byline rather than assume a full personal identity.
For readers, that makes Normanus interesting in a different way: not as a well-documented public figure, but as the voice behind a compact, visually rich piece of local history focused on one of Smithfield's best-known landmarks.
